ANNEALlNG-FURNACE.

SPECIFICATION forming part of Letters Patent No. 586,883, dated July 20,1897. application filed February 13, 1897. fierial No. 623,282. (Nomodel.)

To 1 72 "whom, it wm l concern:

Be it known that I, Janus TIMMS, a resident of Columbus, in the countyof Franklin and State of Ohio, have invented certain new and usefulImprovements in Annealing-Furnaces and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to an improvement in annealing-furnaces, the objectof the invention being to so construct the furnace that the oven can bequickly and etficiently heated uniformly by the consumption of a minimumamount of fuel.

WVith this object in view the invention 0011- sists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a partial longitudinal viewtaken on line G II of Fig. 3. Fig. :3 is a partial sectional view on theline E F of Fig. Fig. 3 is a sectional view on the line M N of Fig. 2.Fig. 4 is a sectional view on the line K L of Fig. 2. Fig. 5 is ahorizontal sectional view on the line C D of Fig. Fig. 6 is a horizontalsectional view on the line A B of Fig. 4.

A represents a suitable base, and B the anhealing-oven.

I11 the front part of the furnace a series of fire-chambers or furnacesG are located, each of which communicates with a series of lines 1,disposed between the base A and the floor Z) of the oven 13, the wallsof said flues being made with expansion-spaces c d. The fines 1 1 havesome refractory material 00, such as sand, in the bottom. The forwardends of the fines 1 communicate with a corresponding number of verticalflues 2, which extend to the crown c of the oven, where they dischargethrough openings 3 into the oven B. The products of combustion, afterpassing through the fines 1 2 and the upper portion of the oven B, entera flue a through openings 5 in the vertical wall of the oven. The

flue 4: it will be observed, is directly over the fire-chambers orfurnaces O, andthe products of combustion will therefore be so highlyheated that the gases will become ignited as they pass through said fine4.. From the flue & the products of combustion pass through a short flue6, located within a structure or enlargement 7 at one end of the furnacestructure, and from said short flue the heated products of combustionpass into a flue 8, which extends the full length of the furnacestructure and directly through the center of the oven B, thuseffectually heating the center of the oven. The flue 8 is preferablyprovided with a number of radiators 9, of ma sonry, and the said flue 8discharges into the stack 10.

By the construction above set forth the annealing-oven B can bethoroughly and uniformly heated and the annealing process can beeffectually accomplished with the expenditure of a comparatively smallamount of fuel.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. In an annealing-furnace, the combina tion with a fire-chamber, andoven, of a flue extending from the fire-chamber beneath the floor of theoven and upward within one side wall of the furnace and discharging intothe top of the oven, and a flue leading from the top of the furnacedownward over the firechamber, a flue beneath the oven to which thislast-1nentioned flue leads, and a flue extending through the oven towhich the flue beneath the oven leads.

2. In an annealing-furnace, the combination with a series offire-chambers and an oven, of a series of fines communicating with eachfire-chamber and located under the floor of the oven, vertical does atone side of the oven and communicating with said first-mentioned flues,said vertical flues discharging into the upper part of the oven, a fluelocated over the series of fire-chambers which receives products ofcombustion from the oven, a flue extending through the oven incommunication with the flue over the fire-chambers and receivingproducts of combustion therefrom and a stack communicating with the fluein the oven, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JAMES TIMMS.
